Its efficacy diminishes beyond 8 hours and diminished further beyond 16 hours post-ingestion. For most people this amount of Tylenol has a half-life in the blood of 125 to 3 hours. Forty-eight patients with no or little hepatotoxicity ALT.
Overall the median acetaminophen half-life was 54 hours range 08-1197 hours. In this randomized single-blind parallel repeat-dose study in healthy adults subjects received four repeat doses of oral or intravenous 1000 mg paracetamol at 6-h intervals and morphine. T - time that has passed since the first original administration of the drug.

In some formulations paracetamol is combined with the opiate codeine sometimes referred to. The evaluation and treatment approach for an IV acetaminophen overdose are similar to those for an oral overdose. 13 The half-life of acetaminophen is approximately 2 to 3 hours after therapeutic doses yet can be increased to.
